Description
Thiazolidinedione (TZD) oral antidiabetic; targets insulin resistance
Used in adults with type 2 diabetes mellitus; not used with insulin due to increased risks for heart failure
Monitor closely; TZDs can cause or exacerbate heart failure (boxed warning)
Indications
Indicated as adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus who are already treated with a meglitinide and metformin, or who have inadequate glycemic control on a meglitinide alone or metformin alone
Contraindications
Hypersensitivity to rosiglitazone
Diabetic ketoacidosis
Heart failure NYHA class III-IV
Active liver disease: do not start rosiglitazone if ALT >2.5 x ULN
Adverse Effects
- Increased LDL-cholesterol
- Increased HDL-cholesterol
- Increased total cholesterol
- Edema
- Hypertension
- Heart failure/congestive heart failure
- Myocardial ischemia
- Diarrhea
- Upper respiratory tract infection
- Accidental injury
- Anemia
- Back pain
- Fatigue
- Headache
- Hypoglycemia
- Myalgia
- Sinusitis
- Weight gain
Warnings
Fluid retention, which may exacerbate or lead to heart failure, may occur; combination use with insulin and use in congestive heart failure NYHA Class I and II may increase risk of other cardiovascular effects
If ALT >3 x ULN stop treatment; if 1.5-3 x normal, retest qWeek until normal or 3 x normal and need to discontinue
Not for use in diabetes mellitus type 1; mechanism requires presence of endogenous insulin; use with insulin may increase risk of heart failure; not recommended
Thiazolidinediones, which are peroxisome proliferator-activated receptor (PPAR) gamma agonists, can cause dose-related fluid retention, particularly when used in combination with insulin; dose-related edema and weight gain may occur
When used in combination with other hypoglycemic agents, a dose reduction of concomitant agent may be necessary to reduce risk of hypoglycemia
Associated with rare cases of new onset or worsening of macular edema
May result in ovulation in some premenopausal anovulatory women; ensure adequate contraception
Increased risk of fractures of upper arm, hand, or foot in female patients
Dose-related decreases in hemoglobin and hemocrit reported
Pregnancy and Lactation
Limited data in pregnant women are not sufficient to determine drug- associated risk for major birth defects or miscarriage
There are no data on presence of rosiglitazone in human milk, effects on breastfed infant, or on milk production
